Instrumentation panel on the bridge of the EU bottom trawler, Ivan Nores, showing tracks of previous trawls in the North East Atlantic. Bottom-trawling boats, the majority from EU countries, drag fishing gear weighing several tonnes across the sea bed, destroying marine wildlife and devastating life on underwater mountains - or 'seamounts'. Greenpeace ship Esperanza tours Atlantic waters searching for and intercepting bottom trawling fishing vessels during a campaign to highlight the destruction caused by this controversial form of fishing.
